SEAT-ACTION FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 598,834, dated February8, 1898.

Application filed December 31,1896. Serial No. 617,666. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE D. ACKLEY, of Fort Worth, in the county ofTarrant and State of Texas, have invented certain new and usefulImprovements in Seat-Action Flushing Apparatus; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being bad to the accompanyingdrawings, which form part of this specification.

This invention relates to an improved seataction flushing apparatus; andthe object is to provide a cistern into which the water is admitted onlywhen the seat is occupied and from which it drains completely when theseat is released, the water draining also from the cistern-supply pipe,so that where the closet is exposed to cold there is no opportunity forthe water to freeze.

A further object is to provide a siphon of improved form.

The invention consists of the novel features of construction hereinafterfully described and claimed, and illustrated by the accompanyingdrawings, in which- Figure 1 is a perspective view of a closet providedwith my improved flushing apparatus. Fig. 2 is an elevation of thecistern, the side thereof being removed to expose the internalmechanism. Fig. 3 is a plan view. Fig. at is a vertical sectional viewof the siphon and inlet. Fig. 5 is a detailed perspective view of theseat-operated crankshaft for starting the flush. Fig. 6 is a verticalsectional view of the cistern-supply valve.

A designates the cistern, and traversing its top is lever B, which isfulcrumed between its ends in chair 0, supported by transverse bar 0'.Adjustably secured to the lever upon one side of the fulcrum is weightD, while de pending from the opposite and projected extremity of thelever is the operating rope or chain E. Upon the upper end of flush-pipeF is siphon G, the leg 1-1 of the siphon being open at its upper andlower ends. Rod I moves vertically in the leg H and carries valves J andJ, adapted, respectively, to seat upon the upper and lower ends of legII by the vertical movement of the rod and thus alternately open andclose said ends-for the purpose presently to be explained. Each valveconsists, preferably, of a rubber washer, which is secured to andadjustable on the rod by a screw-nut, as shown. The upper end of rod Iprojects through keeper B, carried by lever B, and is provided with nutI, whereby the movement of the lever independent of the valve-rod isadjusted and regulated. Supplypipe K extends from the three-way valve Lin the water-main to the cistern, and this valve is operated by weightedarm M, to which the lower end of chain E is secured. Shaft N, having thecentral bend or crank portion N, is loosely mounted to turn on the underside of the fixed portion 0 of the closet-seat. The extremities of theshaft are turned at right angles to its main portion and in oppositedirections, as shown, one end thereof being secured to chain E, whileits opposite extremity is provided with a slight vertical bend where itcarries roller 0, which engages the under side of the seat 0.

In operation when the seat is depressed shaft N is turned and an upwardpull exerted upon chain E, the pull being sufficient to lift weightedarm M of the main valve, thus permitting water to flow throughsupply-pipe K to the cistern. Weighted arm M is sufficient tocounterbalance weight D of lever B, and hence said weight D is normallyraised and the opposite end of lever B depressed. In this position theupper open end of siphonleg His closed and its lower end open. l/Vhen,however, chain E is relieved of the weight of arm M through the mediumof seat-operated shaft N, lever B is caused to swing vertically throughthe action of weight D, and in so doing lifts rod I and raises valve Jfrom its seat and closes the lower valve J. The water continuesto flowinto the cistern until out off by valve P at the upper end of the supply-pipe, said valve being closed by the vertically-swinging floatcarrying arm Q, as will be readily understood. When the seat 0 isreleased, weighted arm N is permitted to drop, with the result that thesupply to pipe K is out off, and at the same time lever B is drawndownward, so as to close the upper end of the siphon-leg and open itslower end, through the medium of valves J and J, whereby the siphon isstarted and the flush set in operation. Nearly all of the water drainsthrough the siphon, and that portion remaining therein passes downwardthrough opening K in the supply-pipe, so that all Water is drained fromthe cistern. Valve L opens communication between supply-pipe K anddrain-pipe B, so that the water remaining in pipe K emptiestherethrough, as does also the residue of the cistern-water, as justexplained. Leg H of the siphon is open at its upper end and providedwith valve J, so that if float-arm Q or valve P should fail to operateto shut off the supply the Water would simply overflow into the siphon,and thence downward through the flush-pipe instead of overflowing thecistern. The closing of the upper end of the siphon-leg is simultaneouswith the opening of its lower end, so that the action of the siphon isin no Way impaired.

A flushing apparatus is thus provided in which no water is permitted tostand in the cistern or to remain in the cistern-supply I pipe,and thusall danger of freezing is avoided. Having thus fully described myinvention,

what I claim, and desire to secure by Letters Patent, is'

An improved water-closet and flushing apparatus comprising a cistern, asupply-pipe therefor, a Weighted vertically-movable arm, a valve in thesupply-pipe actuated by said arm, a siphon-discharge for the cistern, avalve for closing the siphommechanism arranged intermediate saidsiphon-valve and the weighted arm, whereby the weighted arm serves tohold said valve normally open, the crank shaft suitably supported andconnected at one end to said intermediate mechanism, and a depressiblecloset-seat adapted to actuate the opposite end of the crank-shaft,whereby when the seat is depressed the Water-supply is opened and thesiphon is simultaneously closed, substantially as shown and described.

In testimony whereof I affiX my signature in presence of two Witnesses.

GEORGE D. ACKLEY.
